The ISL59885 video sync separator extracts sync timing information from both standard and non-standard video inputs in the presence of Macrovision pulses. The ISL59885 provides horizontal, vertical, and composite sync outputs as well as SD/HDTV detection. An auto input frequency detect feature automatically adapts to a wide range of video standards (it does not need a different RSET resistor for different frequencies). The vertical sync pulse is output on the rising edge of the first vertical serration following the vertical pre-equalizing string. For non-standard vertical inputs, a default vertical pulse is output when the vertical signal stays low for longer than the vertical sync default delay time. The horizontal output gives horizontal timing with pre/post equalizing pulses. Fixed 70mV sync tip slicing provides sync edge detection when the video input level is between 0. 5VP-P and 2VP-P. The ISL59885 is available in an 8 Ld SOIC package and is specified for operation over the full -40°C to +85°C temperature range.
